    • The invention relates to a novel process for producing thereof hydroxyarenes of the general formula (I) in which n represents the numbers 1, 2, 3 or 4, R represents cyano, carboxyl, formyl, nitro, halogen or represents alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylcarbonyl or alkoxycarbonyl, each of which is optionally substituted, and Z represents hydrogen, cyano, nitro, halogen, alkyl, halogenoalkyl, or represents monocyclic or bicyclic, saturated or unsaturated heterocyclyl, heterocyclylamino or heterocyclylimino, each of which is optionally substituted, characterized in that halogenoarenes of the general formula (II) in which n, R and Z are each as defined above and X represents halogen are reacted with 3-hydroxy-propionitrile of the formula (III), HO—CH2CH2—CN  (III), if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, at temperatures between 0° C. and 100° C.
    • 本发明涉及一种制备通式(I)的羟基芳烃的新方法,其中n代表数字1,2,3或4,R代表氰基,羧基,甲酰基,硝基,卤素或代表烷基,烷氧基,烷硫基, 烷基亚磺酰基,烷基磺酰基,烷基羰基或烷氧基羰基,其各自任选被取代,Z表示氢,氰基,硝基,卤素,烷基,卤代烷基,或表示单环或双环饱和或不饱和的杂环基,杂环基氨基或杂环基, 其特征在于通式(Ⅱ)的卤代芳烃,其中,R和Z各自如上所定义,X代表卤素与式(III)的3-羟基 - 丙腈反应,如果合适,在反应助剂和 如果在稀释剂存在的情况下适当,在0℃至100℃的温度下
